Question

В первой канистре было в 5 раз больше бензина, чем во второй. Весь бензин из этих канистр вылили в пустой бензобак автомашины. Если в этот бак долить ещё 7 л бензина, то он окажется полным. Сколько литров бензина было в каждой канистре, если ёмкость бензобака 55 л?

Answer 1

х - литров бензина во второй канистре.

5х литров бензина в первой канистре.

5х+х+7=55

6х=55-7

6х=48

х=48:6

х=8 (л) - во второй канистре

8* 5 = 40 ((л) - в первой канистре.

Answer 2

55-7=48 кол-во бенз в канистрах 5x+x=48 6x=48 X=8 В первой канистре 8•5=40 Во второй 8

Answer 3

Problem Analysis

We are given two containers, and the first container has 5 times more gasoline than the second container. The total amount of gasoline from both containers is poured into an empty fuel tank of a car. If an additional 7 liters of gasoline are added to the tank, it will be full. We need to determine the amount of gasoline in each container, given that the fuel tank has a capacity of 55 liters.

Solution

Let's assume that the amount of gasoline in the second container is x liters. According to the problem, the first container has 5 times more gasoline than the second container, so the amount of gasoline in the first container is 5x liters.

When the gasoline from both containers is poured into the fuel tank, the total amount of gasoline in the tank is (5x + x) liters, which simplifies to 6x liters.

If an additional 7 liters of gasoline are added to the tank, it will be full. Therefore, the total amount of gasoline in the tank after adding 7 liters is 55 liters.

We can set up the following equation to solve for x:

6x + 7 = 55

Simplifying the equation:

6x = 55 - 7 6x = 48 x = 48 / 6 x = 8

So, the second container initially had 8 liters of gasoline, and the first container had 5 times more, which is 5 * 8 = 40 liters of gasoline.

Answer

Therefore, there were 40 liters of gasoline in the first container and 8 liters of gasoline in the second container.
